Abstract
Conformational Analysis of Acylated 5,6,7,8‐TetrahydropterinesThe conformation of N(5)‐acetates, and of N(5)‐ and N(8)‐trifluoroacetates, respectively, of 6‐methyl‐ and cis‐6, 7‐dimethyl‐tetrahydropterines is studied by 1H‐NMR. spectroscopy. It is shown that the methyl group next to the acylated nitrogen atom is in quasi‐axial position.
